Converting
Wherever running web products are manufactured, processed or finished, two factors are critical for the quality of the finished product: constant tension and the consistent lateral position of the web. FMS closed loop control systems for web tension and web guiding continually maintain all the relevant parameters to ensure precise compliance with the reference values. At the same time, these values are made available for comprehensive recording for quality assurance purposes.

FMS Web Tension Measurement
The web tension in the material (FB) causes a resulting force in the direction of the bisecting line (FM) on a wrapped roller. The measurement of this force is a direct measure of the web tension. The feedback value can be sent to an FMS closed loop tension controller, which regulates a drive, brake, or clutch, ensuring constant material tension throughout the process.

FMS Web Guiding
The actual position of the web is detected by a sensor. The web guide controller compares the measured position value with the pre-set reference value and controls the drive of a steering frame. The steering frame ensures a stable web position by pivoting the steering frame rollers to guide the material.
